surface topography and ultrastructure of dried cysts of artemia parthenogenetica (vedaranyam population) and bisexual artemia sp. (kelambakkam population) were studied electron microscopically in order to identify the bisexual strain, inhabiting covelong salterns, kelambakkam, south india. the scope of this study is to provide substantial information for further characterization of these artemi...

The effects of Al2O3 content on the morphology and reducibility sinter were respectively investigated using confocal laser microscopy thermogravimetric analysis at 1273 K under CO gas. To understand sintering process, separate samples prepared via equilibrium metastable reaction routes. In samples, addition led to formation silico-ferrite calcium alumino phase a decrease in reduction rate due l...

The evolution of the microstructure an AlSi7Cu3 alloy is investigated by optical microscopy and X-ray tomography in as-cast condition with subsequent solution treatments for 2 h 30 min 50 at 495 °C, respectively. analyzed contains pores hard inclusions, i.e. eutectic Si, iron-intermetallics, Al2Cu phases. 2D microscopic surface examination was performed to reveal characteristics Si phase while ...

Tungsten has been chosen as the plasma-facing material (PFM) for divertor region in ITER and also a candidate PFM future plasma-burning nuclear fusion reactors. During device operation, PFMs will be exposed to low-energy He irradiation at high temperatures, resulting sub-surface bubbles surface morphology changes such pores fuzz. Carbide dispersion-strengthened W materials may enhance ductility...

Extreme miniaturization implies a high degree of optimization, rendering the retention non-functional organs almost impossible. Two unique non-porous placoid sensilla on antennae females Megaphragma were described in literature. Placoid Hymenoptera have an olfactory function and always bear pores; apparent absence pores therefore raises questions whether such are functional their surface sculpt...

Organic matter (OM) in continental shale serves as both the source of oil and gas storage space unconventional petroleum systems. However, directly identifying types organic under SEM is challenging when simultaneously observing minerals pores. Kong2 Member(E2k2) Paleogene Cangdong sag Bohai Bay basin a typical layer China. Based on positioning observation technology combining field emission sc...
